如何将for循环的值添加到文本框中

问题描述

private void Window_Loaded_1(object sender, RoutedEventArgs e)
   {
      int ymax = 500;
      parentchart.Axes.Add(new LinearAxis() { Minimum = 0, Orientation=AxisOrientation.Y, Maximum = ymax > 0 ? ymax : 300 });
      txty.Text = ymax.ToString();
      List<int> inp = new List<int>();
      for (int i = 0; i <= ymax; i++)
         {
            inp.Add(i);
            textbox.Text = inp.ToString();
            cmbb.ItemsSource = inp;
            cmbb.SelectedIndex = 0;
         }
   }

这里我想让文本框包含0到500之间的值，应该在文本框中垂直scorlling



它是一个wpf应用程序

here i want to make that textbox should contain value from 0 to 500 and there should be vertical scorlling in the textbox

its an wpf application

推荐答案

textbox.Text += inp.ToString();

或更好，请使用StringBuilder：

or better, use a StringBuilder:

StringBuilder sb = new StringBuilder;
string sep = "";
for (int i = 0; i <= ymax; i++)
   {
      inp.Add(i);
      sb.AppendFormat("{0}{1}", sep, inp);
      sep = ",";
      cmbb.ItemsSource = inp;
      cmbb.SelectedIndex = 0;
   }
textbox.Text = sb.ToString();

但是......你可能想要移动 cmbb 循环外的行。

But... you probably want to move the cmbb lines outside the loop as well.

private void Window_Loaded_1(object sender, RoutedEventArgs e)
   {
      int ymax = 500;
      parentchart.Axes.Add(new LinearAxis() { Minimum = 0, Orientation=AxisOrientation.Y, Maximum = ymax > 0 ? ymax : 300 });
      txty.Text = ymax.ToString();
      List<int> inp = new List<int>();
      for (int i = 0; i <= ymax; i++)
         {
            inp.Add(i);
            textbox.Text = inp.ToString();
            cmbb.ItemsSource = inp;
            cmbb.SelectedIndex = 0;
         }
   }

textbox.Text + = inp.ToString（）;







StringBuilder sb = new StringBuilder;

string sep =;

for（int i = 0; i< = ymax; i ++）

{

inp.Add（i）;

sb.AppendFormat（{0 } {1}，sep，inp）;

sep =，;

cmbb.ItemsSource = inp;

cmbb.SelectedIndex = 0;

}

textbox.Text = sb.ToString（）;

textbox.Text += inp.ToString();



StringBuilder sb = new StringBuilder;
string sep = "";
for (int i = 0; i <= ymax; i++)
{
inp.Add(i);
sb.AppendFormat("{0}{1}", sep, inp);
sep = ",";
cmbb.ItemsSource = inp;
cmbb.SelectedIndex = 0;
}
textbox.Text = sb.ToString();
